I put together a fan out of spare computer parts, I found a 15V 1.4A DC wall adapter in my junk bin as my power supply, but I was short a high wattage 2-5 ohm resistorI have two 120mm PC fans, 12VDC and 0.35A each, wired parallelI cannot hook that up directly to the adapter, I calculated a 3-5 Ohm series resistor would be suitable, perhaps 10 wattsrather than go out and buy the proper resistor (which might be expensive and hard to find) I improvised with a pencilIts a regular 2HB pencil, roughly 4 inches gives me about 3 ohmsI put it in series between the fans and wall adapterI'm wondering was that a good makeshift resistor choice? what would be the approximate wattage capacity of a 2 HB pencil (its made out of wood with plastic/graphite core)? any chance of a fire?the pencil does get uncomfortably hot during the fan's operation-thanks.
The wood enclosure of the pencil is inflammable, and so good a thermal insulator, that even at low power dissipation there's a chance of fireIIRC a standard pecil lead is graphite and ceramic, not plasticWhy not air cool the resistance element?
Your final product will turn out best with a bit of salt in the doughSalt keeps the yeast form going crazy, kind of holds it in checkGarlic also has this effect, so try using half salt, half garlic and see how you like it Whole Wheat Challah Bread You can just shape it into any size loafIt makes 2 challah (braided) loavesThis has two risings, and takes about 4 hours 4 cups whole wheat flour 1/2 cup sugar 1 pkg yeast (2? tsp) 1 tsp salt 2 eggs for dough 1 egg for egg wash 1 cup plus 1 tsp water Measure flour, sugar and salt into a small bowl and stirIn a large separate bowl, pour 1 cup warm water; add yeast and stirLet sit for 5 minutesAdd 1? cups of the flour mixture, beat, and coverLet sit for 30 minutesAdd two eggs, beatAdd the rest of the flour mixture and knead for 10 minutesLet sit covered for 1 hourPunch down dough, break into two piecesBreak each piece into 3 smaller ones and roll into snakesBraid snakes into two loaves, being sure to pinch the ends togetherLet sit covered for about 2 hoursMix 1 egg and 1 tsp water and gently brush over loavesBake 10 minutes at 400?F; reduce heat to 375?F and continue baking until a nice crust forms and it looks perfect (anywhere from 2-8 minutes).
